Flawless diamond to be auctioned
An exceptionally rare 102.39-carat diamond may bee one of the most expensive stones ever to sell at auction when it goes under the hammer in Hong Kong next month.
Although auction house Sotheby's declined to provide a pre-sale estimate
diamonds of similar size and quality have previously attracted bids anywhere from $12 million to more than $30 million.
尽管苏富比拍卖行拒绝提供预售估价，但此前拍卖的尺寸和质量相似的钻石的成交价从1200万美元到超过3300万美元不等。
Cut from a 271-carat rough diamond discovered in 2018 in Ontario
Canada
the oval stone has achieved top rankings in each of the "four Cs" - cut
color
clarity and carat weight - by which a diamond is judged
the auction house said.
It has been classified as "D color
" the highest grading for a white diamond
and is considered to be internally and externally "flawless
" placing it among the world's most chemically pure
transparent and symmetrical diamonds.
It also belongs to a rare subgroup of diamonds that contain little to no nitrogen.
Only seven D color flawless (or internally flawless) diamonds weighing more than 100 carats have ever appeared at auction before
according to Sotheby's.
Unusually
the rare oval diamond is being offered without a reserve
meaning it will be sold regardless of the size of the highest bid.
Bidding will open online from Sept 15
with the sale concluding at a live auction in Hong Kong on Oct 5.
